Info Product Finder 7.1 Description of the symbols for performance characteristics L + Length adjustment With the length adjustment, the projection length of the quick-change adapter can be re-adjusted or increased in case of need. L+ 2 mm Length adjustment by 2 mm The projecting length of the tool can be extended by 2 mm (0.0787 inch) with the length adjustment screw. Drilling and countersinking Drilling and countersinking operations can be done without exchanging the quick-change holder, simply by blocking the length compensation with a locking screw. The resulting advantages are: • Alignment offset between drilled hole and thread reduced to a minimum • No time-consuming re-tooling, with according cost reduction Tool adaption by means of quick-change adapters, EM series The quick-change adapters of our EM series have been designed for use in the quick-change tap holders of our KSN and SFM series. The five sizes have been divided into corresponding thread size ranges, and are available in different types. The adaption of the tool is made by means of a quick-change ball clamping system in most quick-change adapters, with a separate adapter being necessary for each shank diameter. Our quick-change adapters are suitable for the production of right-hand and left-hand threads. Tool adaption by means of quick-change adapters, HE series The tool adaption is effected by means of quick-change adapters of our HE series. The clamping of the tool is provided by threaded pins. For our adapters type HE 2/IKZZ, we recommend a fastening torque of 11.06 ft lbs / 15 Nm. Tool adaption by means of collets, type ER (GB) The tool adaption is effected by means of collets of our ER, or our ER-GB series (with integrated square) acc. DIN ISO 15488 (formerly DIN 6499). This type of clamping helps to achieve very good concentricity and a safe clamping of the tool, especially with high cutting speeds and coolant pressures. Tool adaption by means of collets, type PGR-GB The tool adaption is effected by means of collets of type PGR-GB (with integrated square).
